Homemade Orange Liqueur is surprisingly easy to make and is intense and sweet with the aromatic flavor of oranges. It is also so much tastier and a cheaper alternative to make it yourself than to buy an expensive bottle of Grand Marnier.
Double the sugar and water for a sweeter liquor if desired. For sipping liquor I recommend less sugar but if you will mostly be using your Homemade Orange Liqueur in cocktails you may want to add more simple syrup mixture.
